"Our brief was to develop a modern performance diesel engine that meets the Euro 5 standard," said Derek Crabb, Volvo Vice President, Powertrain Engineering. "When the project got under way, our goal was to bring fuel consumption down to 6.4 lt /100km (44.1mpg UK) in the S80, which, after all, is a relatively large car," recalls Derek Crabb.
"As the work progressed, we saw that we could beat that target and today we are actually down to 6.2 lt / 100km (45.6mpg UK). With an automatic gearbox we have been able to reduce the consumption by more than 8 percent, from 7.3 to 6.7 lt / 100km (38.7 to 42.2mpg UK), which is a significant improvement."
The new D5 diesel will be available in the S80 in the second quarter of 2009 while it certain that Volvo will offer the engine in other models, including the forthcoming S60 sedan.
